Abstract

The invention provides a magnetorheological fluid turbine damper. A wheel frame is fixed in a cylinder body through an inner passage frame, the main part of a blade is provided with wire slots around,magnet exciting coils are wound on the wire slots, air guide sleeves are arranged peripheries of the wire slots, pump wheels are fixed to an input shaft through blade root disks, guide wheels are fixed to the wheel frame, the pump wheels and the guide wheels are arranged alternately, and the input shaft can rotate freely in a blade end ring. The magnetorheological fluid turbine damper further comprises an electric collector socket, and the electric collector socket is connected with an external adjustable current to transmit power to the magnet exciting coils of the guide wheels and to the magnet exciting coils of the pump wheels through collector rings. The magnetorheological fluid turbine damper controls high of damper damping by energizing the magnet exciting coils of one or several blades, and at the same time, can be applied in an occasion with high damping force precision by cooperating with a valve damper and controlling high of an input current through an external. The magnetorheological fluid turbine damper has the characteristics of high braking efficiency. The damper is mainly applied in rotating occasions, shafting deceleration, and shaft brake.

Description

technical field [0001] The invention relates to the field of semi-active vibration control, and relates to a magnetorheological fluid turbine damper. Background technique [0002] The turbine damper has the advantages of simple structure, no complicated control system and easy maintenance. In the work of the damper, the static liquid is stirred by the rotor blade to generate a damping force acting on the surface of the rotor blade, forming a damping torque, and finally decelerating the object. The kinetic energy of the object is converted into the internal energy of the liquid medium. It is manifested as an increase in the temperature of the liquid medium. [0003] The magnetorheological fluid damper has the advantages of low energy consumption, large damping force and continuous adjustment, fast response speed, and high working temperature. risk. In special cases, even if the energy supply is lost, effective passive control can still be carried out. However, the existi...
